Steroetypes in our society

Why do you think that stereotypes are so widely known by so many in our society? I believe that sterotypes are widley known in our society because there are so many different races, and different ethnic backrounds in the world. Everyone always says i dont sterotype, but they do it and dont even notice it. Also everyone was brought up differently, and maybe their families told them things about that race or another. People think there are only stereotypes for whites and blacks, but there are stereotypes for every race in the world. I think stereotypes are made by cultures that people believe in, how people dress, what they eat, and what they look like.
